It seems that something like this could happen over time naturally if it's a saying that "everyone knows" so that real meaning stops being said, and then eventually that bit of information disappears. For instance KISS "Keep it simple, stupid" has a negative connotation, but the idea is very sound. So people keep saying the abbreviation but stop saying the full version, and new people hearing it the first time might get the basic idea without knowing why. Eventually even the meaning could be lost, and it could just become something that people say without knowing why. Maybe the assume the ancient designers and engineers liked to make out when they saw complex things. [[User:Andyd273|Andyd273]] ([[User talk:Andyd273|talk]]) 17:58, 25 October 2024 (UTC)

This is similar to the number 42 in Hitchhikers Guide to the Galaxy, in that the answer is known, but the exact question (=the context) has been lost. See [https://hitchhikers.fandom.com/wiki/42 HHGG Fandom wiki] --[[User:Cavac|Cavac]] ([[User talk:Cavac|talk]]) 09:33, 28 October 2024 (UTC)

Minor grammatical point; please feel free to skip this. I just tweaked "a communication technique [...] which meaning has not been lost." to "a communication technique [...] whose meaning has not been lost.". "''Of'' which ''the'' meaning" or "whose meaning" both work, but the latter is less contrived. People keep forgetting that "whose" can refer to objects, as well as to people. <https://en.wiktionary.org/wiki/whose#Determiner>

The first rule of communication is "Always talk about communication." [[User:RegularSizedGuy|RegularSizedGuy]] ([[User talk:RegularSizedGuy|talk]]) 15:36, 25 October 2024 (UTC)

I'm pretty sure the first rule is "Context Matters" and "Helix Sandwich" conveys that by the lack of it.[[Special:Contributions/172.70.126.228|172.70.126.228]] 20:28, 27 October 2024 (UTC)

Possibly the best real-world example of this is the Biblical Book of Revelation. It's an example of apocalyptic writing, which means 'writing in code', not necessarily 'talking about the end of the world' (although it does also do that, which is where the confusion has arisen). And that's sort of the point - most of the context which would enable us to understand the book properly has been lost. For example, scholars generally accept that the 'beast' whose number is 666 is a reference to a real historical person, and that the number 666 is supposed to tell the reader that person's identity... but there's no consensus on who that person is. The fact that there is evidence to suggest that the number was altered (from 616) by later editors doesn't help. [[Special:Contributions/172.70.90.109|172.70.90.109]] 05:47, 28 October 2024 (UTC)

I don't think the "helix" refers to software development. It could be about the helical model of communication, which conveys communication as a non-linear process.

This is perhaps a joke with these simplistic "rules" of communication (like the compliment sandwich), which portray communication as something much simpler.

If we assume that communication is complex and non-linear (as the helical model of communication portrays), we might conclude that there is no such thing as "#1 rule of communication"; something that could be observed by the misuse of the "compliment sandwich". {{unsigned ip|172.70.47.87|15:38+, 25 October 2024}} (Assuming all the above is the same IP editor, tweaking their comment.)

:Ah, thank you. I added the Spiral (for development) because I couldn't find the Helix one (for communication), and I thought this was the best linkable item out there. Now I know it's ''Helical'', I've found it and I can put a link on your addendum and perhaps remove my original 'placeholder'.

I took the opposite point from that in the explanation so far, especially with the title text: Even if the encoding is wrongly specified, it's possible to figure out what was meant by some sequence of bytes. I imagine the teacher using a different nonce every time to make the point about the #1 rule of communication: Words don't have inherent meaning, it is acquired through use. (Though if I'm the only one with this interpretation it kind of sinks my idea I guess). [[User:Hcs|Hcs]] ([[User talk:Hcs|talk]]) 10:18, 26 October 2024 (UTC)

Is it not true that Cueball could basically be demonstrating the #1 rule, i.e. context is important, and that sometimes language is self-repairing? [[Special:Contributions/172.69.214.109|172.69.214.109]] 14:42, 26 October 2024 (UTC)

What's random about Fahrenheit? (Answer: nothing.) 0F is the freezing point of brine, 100F (or 98.7) is the human body temperature. [[Special:Contributions/172.68.54.65|172.68.54.65]] 00:00, 22 October 2024 (UTC)
:What concentration of brine? (And which specific salt... No, not NaCl, as you might presume but NH4Cl!)
:And body temperature varies a lot ('typically' 36.5–37.5°C or 97.7–99.5°F, though even this range is thought to be too small), across genders, individuals, time of day ''and'' which orifices/surfaces you try to measure it from. (Originally, it was set so that '''90°F''' was to be the 'best guess' of human body temperature. It gradually changed, including via various {{w|Human body temperature#Historical understanding|compounded misunderstandings}} so that the best you can say is that 100°F is arbitrarily ''slightly above'' most afebrile human body temperature measurements.)

Sorry, Randall, for my comfort, Fahrenheit is the least cursed. It's the best scale to use for my personal use, especially when hearing the weather report and deciding what to wear outdoors: temp in the 80's - no jacket. temp in 70's - maybe a windbreaker if it's breezy. 60's - sweater weather. 50's - medium weight coat. 40's - winter coat. 30'3 - winter coat with scarf and gloves. 20's - multiple layers. teens - stay indoors. None of the other scales provide such convenient distinctions for my daily life. Kelvin is great for astro physics or super conductivity, but useless for any common uses. Celsius is great for hanging out with the Euro crowd but still not so useful to scale my home thermostat. I judge Fahrenheit as 1.0 for cursedness.

Every temperature scale is equally "random" as every other scale. People always say that Celsius is so much better because it's defined by the phase changes of water. Okay, cool...why should THAT of all things be what we use as the base for a system of temperature measurement? And, who cares? I'm a ''Homo sapiens'', not a water molecule{{cn}}. If anything we should use the freezing and melting points of humans as our two reference points for temperature (which, I must say, Fahrenheit approximates better than Celsius, assuming 0 and 100 are your points "A" and "B").

: Every temperature scale is arbitrary, but since boiling and freezing water is a thing humans have a lot of experience with it makes sense to use that as the reference point.

::::Chat Gippity told me:

:::::Black holes and neutron stars do not typically involve temperatures reaching the Planck scale. While both objects exhibit extreme physical conditions, their temperatures are far below the Planck temperature, even though they can be incredibly high compared to everyday phenomena.

::::: - **Neutron stars** have surface temperatures in the range of millions of Kelvin, and the core can reach even higher, possibly up to a few billion Kelvin. These temperatures are still vastly lower than the Planck temperature.

::::: - **Black holes**, especially the smaller ones, can emit Hawking radiation, with temperatures inversely proportional to their mass. However, the temperature of even a very small black hole is still far below the Planck temperature. Hawking radiation is not expected to reach temperatures close to the Planck scale under normal circumstances.

::::: The Planck temperature (TP=1) represents an energy scale so extreme that no known physical models, including those describing black holes and neutron stars, operate near or above this threshold. Temperatures reaching **0.0000001 TP** (or 1.416 × 10^26 K) would still be beyond current observational and theoretical frameworks related to these cosmic objects. A quantum theory of gravity would be required to describe physics at or near the Planck temperature, which remains speculative and is far beyond the conditions found in black holes or neutron stars.

If the °X scale is based on the temperatures of Earth from all time (for some definition of "Earth"), then the scale is very hard to define and highly impractical. The earth appears to have gotten to more than 2,300 Kelvin (hot enough to melt steel and platinum and to boil lead) and while I can't find any sources for the lowest temperature, I imagine it is lower than -100°C. The recorded minimum, maximum and average temperatures appear to be around -89.2 °C, 56.7 °C and 15 °C respectively. This would make the scale somewhat useful, but this would make typical values between 41 °X (cold winter's day) and 68 °X (hot summers day) which I think is pretty cursed. I recommend the clearly superior °Y, based around average temp at 0 °Y, low at -100 °Y and high at 100 °Y. These would be measured by the yearly high, low and mean temperatures averaged per person. Then saying "It's 2 times colder than yesterday" would have some reasonable meaning. --[[Special:Contributions/198.41.236.147|198.41.236.147]] 04:01, 22 October 2024 (UTC)

What's random about Fahrenheit? (Answer: nothing.) 0F is the freezing point of brine, 100F (or 98.7) is the human body temperature. [[Special:Contributions/172.68.54.65|172.68.54.65]] 00:00, 22 October 2024 (UTC)
:What concentration of brine? (And which specific salt... No, not NaCl, as you might presume but NH4Cl!)
:And body temperature varies a lot ('typically' 36.5–37.5°C or 97.7–99.5°F, though even this range is thought to be too small), across genders, individuals, time of day ''and'' which orifices/surfaces you try to measure it from. (Originally, it was set so that '''90°F''' was to be the 'best guess' of human body temperature. It gradually changed, including via various {{w|Human body temperature#Historical understanding|compounded misunderstandings}} so that the best you can say is that 100°F is arbitrarily ''slightly above'' most afebrile human body temperature measurements.)

Sorry, Randall, for my comfort, Fahrenheit is the least cursed. It's the best scale to use for my personal use, especially when hearing the weather report and deciding what to wear outdoors: temp in the 80's - no jacket. temp in 70's - maybe a windbreaker if it's breezy. 60's - sweater weather. 50's - medium weight coat. 40's - winter coat. 30'3 - winter coat with scarf and gloves. 20's - multiple layers. teens - stay indoors. None of the other scales provide such convenient distinctions for my daily life. Kelvin is great for astro physics or super conductivity, but useless for any common uses. Celsius is great for hanging out with the Euro crowd but still not so useful to scale my home thermostat. I judge Fahrenheit as 1.0 for cursedness.

Every temperature scale is equally "random" as every other scale. People always say that Celsius is so much better because it's defined by the phase changes of water. Okay, cool...why should THAT of all things be what we use as the base for a system of temperature measurement? And, who cares? I'm a ''Homo sapiens'', not a water molecule{{cn}}. If anything we should use the freezing and melting points of humans as our two reference points for temperature (which, I must say, Fahrenheit approximates better than Celsius, assuming 0 and 100 are your points "A" and "B").

: Every temperature scale is arbitrary, but since boiling and freezing water is a thing humans have a lot of experience with it makes sense to use that as the reference point.

::::Chat Gippity told me:

:::::Black holes and neutron stars do not typically involve temperatures reaching the Planck scale. While both objects exhibit extreme physical conditions, their temperatures are far below the Planck temperature, even though they can be incredibly high compared to everyday phenomena.

::::: - **Neutron stars** have surface temperatures in the range of millions of Kelvin, and the core can reach even higher, possibly up to a few billion Kelvin. These temperatures are still vastly lower than the Planck temperature.

::::: - **Black holes**, especially the smaller ones, can emit Hawking radiation, with temperatures inversely proportional to their mass. However, the temperature of even a very small black hole is still far below the Planck temperature. Hawking radiation is not expected to reach temperatures close to the Planck scale under normal circumstances.

::::: The Planck temperature (TP=1) represents an energy scale so extreme that no known physical models, including those describing black holes and neutron stars, operate near or above this threshold. Temperatures reaching **0.0000001 TP** (or 1.416 × 10^26 K) would still be beyond current observational and theoretical frameworks related to these cosmic objects. A quantum theory of gravity would be required to describe physics at or near the Planck temperature, which remains speculative and is far beyond the conditions found in black holes or neutron stars.

If the °X scale is based on the temperatures of Earth from all time (for some definition of "Earth"), then the scale is very hard to define and highly impractical. The earth appears to have gotten to more than 2,300 Kelvin (hot enough to melt steel and platinum and to boil lead) and while I can't find any sources for the lowest temperature, I imagine it is lower than -100°C. The recorded minimum, maximum and average temperatures appear to be around -89.2 °C, 56.7 °C and 15 °C respectively. This would make the scale somewhat useful, but this would make typical values between 41 °X (cold winter's day) and 68 °X (hot summers day) which I think is pretty cursed. I recommend the clearly superior °Y, based around average temp at 0 °Y, low at -100 °Y and high at 100 °Y. These would be measured by the yearly high, low and mean temperatures averaged per person. Then saying "It's 2 times colder than yesterday" would have some reasonable meaning. --[[Special:Contributions/198.41.236.147|198.41.236.147]] 04:01, 22 October 2024 (UTC)

==Explanation==
{{incomplete|Created by a GIANT AUSTRALICAN SPIDERIGATOR - Please change this comment when editing this page. Do NOT delete this tag too soon.}}

This is the eighth comic in the series of [[:Category:Bad Map Projections|Bad Map Projections]] displaying Bad Map Projection #102: The United Stralia. It follows [[2951|#45: Exterior Kansas]], released about three and a half months earlier. In this addition to the Bad Map Projections series, Randall has blended two different countries — the United States of America and Australia — into one.

As with a number of Bad Map Projections, the primary joke is the naming of this ''as'' a "map projection". Its depiction is particularly similar to [[2807: Bad Map Projection: ABS(Longitude)]], in which geography is overlaid upon other geography. It also follows the practice of [[2256: Bad Map Projection: South America]], in which a general continental shape is forced upon other areas, with the general geographical outline of the 48 contiguous US states being merged with the political boundaries of Australia (with exceptions, most obviously Australia's Bass Strait being retained in lieu of the US's central Florida). At a further level of merging, the US states are repacked as subdivisions within the various Australian ones; as with the likes of [[2394: Contiguous 41 States]], it also takes some liberties with the relative neighboring positioning of some of these, although not by totally removing any of the actual {{w|contiguous United States}}. Alaska and Hawaii aren't included, likely because the 48 contiguous US states better match the shape and size of Australia. Australia also has no equivalent of Alaska and Hawaii.

The geographically relative climate of the states of the USA is broadly opposite of Australia's. Australia's north is closest to the equator but the USA's north is farthest from the equator. Thus, if Australia's climate were literally applied to the US, Florida would be relatively cold while Maine would be hot. Likewise, applying USA's climate to Australia would make northern Australia unusually cold and southern Australia relatively hot.

The map pokes fun at superficial and irrelevant similarities between features of the maps of the United States and Australia, such as the shape of the east coasts of {{w|New England}} and the {{w|Cape York Peninsula}}, and the distance to the southern tip of the island of {{w|Tasmania}} and the length of the {{w|Florida}} {{w|peninsula}}. The end result is to illustrate a fanciful place which does not actually exist and thus would have limited worth for navigating either Australia or the USA, although navigation between two listed locations/areas drawn from the same original continent would at least be broadly possible (with the possibility of a few 'surprises' en route). The blending features cities from both countries on the map, e.g., San Francisco and Los Angeles (USA) close to Perth (Australia).

The {{w|states and territories of Australia}} are depicted with black lines/labels, while the {{w|states of the United States}} and such cities as are taken from either nation are marked with gray. The Australian states are labeled with their full names, but the American states are given only their postal abbreviations. (Mississippi is mislabeled as MI, in addition to Michigan's own correct usage, instead of the official MS.) Western Australia is usually abbreviated to WA, but the convention here leaves that unambiguously assigned to the US state of Washington. Idaho, for some reason, is not labeled at all, and neither is the Australian island state of Tasmania.

The title text makes a joke that this map does not preserve {{w|Equal-area projection|area}} or {{w|Conformal map projection|direction}} (typically, a map projection {{w|Map projection#Metric properties of maps|sacrifices one to preserve the other}}, or both to correctly depict a particular distance metric), but does preserve the city of Melbourne as a feature located on the map, near the actual location of {{w|Melbourne, Florida}}. Note that this is not the correct location of {{w|Melbourne}}, Australia, as it is far too much east in the bad map projection, but there is nothing to stop the shared Melbourne being entirely 'correct' and every ''other'' feature being shifted as a 'compromise'. The concept of a point being 'preserved', rather than actual dimensionally-meaningful quantities, is meaningless and just adds to the badness of the projection. There are other city names shared between the US and Australia, but they're not located at any obviously similar geographic locations; e.g., the location of Brisbane in the comic is based on the instance in {{w|Brisbane|Queensland}}, not {{w|Brisbane, California|California}} (potentially named after the main example) or {{w|Brisbane, North Dakota|North Dakota}}.

This is the second comic in October 2024 in which Tasmania appears, the first being [[2996: CIDABM]]. Both feature the major island groups in the Bass Strait, in this case perhaps intended as a sort of analogue to the {{w|Florida Keys}}, or else orphaned coastline features across the 'missing' segment of the US peninsula.

===Geographical relationships===
From west to east, the Australian states and territories contain the following U.S. states; the positions of Australian cities on the map are also listed:

{{w|Western Australia}} contains the following U.S. states:
*Arizona
*California
** {{w|Perth, Australia|Perth}} appears on the California coast, about halfway between {{w|Los Angeles}} and {{w|San Francisco}}.
* Colorado
* Idaho
* Montana
* Nevada
* New Mexico
* Oregon
* Utah
* Washington
* Wyoming

{{w|Northern Territory}} contains the following U.S. states:
* Illinois
* Iowa
* Kansas
* Michigan ({{w|Upper Peninsula}})
* Minnesota
** {{w|Darwin (Australia)|Darwin}} is positioned in northwestern Minnesota.
* Missouri
* Nebraska
* North Dakota
* South Dakota
* Wisconsin

{{w|South Australia}} contains the following U.S. states:
* Arkansas
* Louisiana
** {{w|Adelaide, Australia|Adelaide}} is located in the {{w|Mississippi River delta}} region of Louisiana.
* Oklahoma
* Texas

{{w|Queensland}} contains the following U.S. states and territories:
* Connecticut
* Delaware
* District of Columbia
* Indiana
* Kentucky
* Maine
* Maryland
* Massachusetts
* Michigan ({{w|Lower Peninsula}})
* New Hampshire
* New Jersey
* New York
* North Carolina
** {{w|Brisbane}} is located on the coast in southeast North Carolina.
* Ohio
* Pennsylvania
* Rhode Island
* Tennessee
* Vermont
* Virginia
* West Virginia

{{w|New South Wales}} contains the following U.S. states:

* Alabama
* Georgia
** {{w|Canberra}}, and presumably the rest of the {{w|Australian Capital Territory}}, is located in southeastern Georgia.
* Mississippi
* South Carolina
** {{w|Sydney, Australia|Sydney}} is located along the coast of South Carolina, near the location of {{w|Charleston, South Carolina|Charleston}}.

{{w|Victoria, Australia|Victoria}} and {{w|Tasmania}} combine to make up the U.S. state of Florida, which is now divided into two non-contiguous parts. As a result Tasmania, which has a {{w|Omission of Tasmania from maps of Australia|history of being omitted from maps of Australia}}, is displayed but not named. {{w|Melbourne}} is located in the southeast corner of Victorian Florida. Although Tasmania's largest city {{w|Hobart}} is not labeled, it could share the same general location of Miami on the map. Alaska and Hawaii, the two non-{{w|Contiguous United States|contiguous states}} of the United States, do not appear in the projection. Other major geographic distortions include:
* The U.S. now has two {{w|quadripoint}}s, with the intersection of Colorado, Kansas, Oklahoma, and New Mexico joining the existing {{w|Four Corners}}.
* Indiana has a border with Arkansas.
* Alabama and Mississippi have lost Gulf Coast access, as Florida has a border with Louisiana.
* Missouri has a north-south border with Oklahoma.
* {{w|Miami, Florida|Miami}} is separated from the lower 48 states, as it is now located in the non-contiguous Tasmanian Florida.

==Trivia==
The use of "Stralia" in the title echoes a common Australian verbal abbreviation for the country, often styled something like '''Stralia'', in casual speech or sometimes {{w|Elsa Stralia#Stage name|more formally}}. This is a convenient punny replacement of the word "States" in "The United States", as it starts with the same two letters.

On the day this comic was released, the xkcd homepage changed to show a [[:File:xkcd_homepage_strip_harris_for_president.png|strip]] showing [[Cueball]] installing a "Harris For President" sign in some grass, presumably on his lawn. This relates to the upcoming 2024 US presidential election.

==Explanation==
{{incomplete|Created by a GIANT AUSTRALICAN SPIDERIGATOR - Please change this comment when editing this page. Do NOT delete this tag too soon.}}

This is the eighth comic in the series of [[:Category:Bad Map Projections|Bad Map Projections]] displaying Bad Map Projection #102: The United Stralia. It follows [[2951|#45: Exterior Kansas]], released about three and a half months earlier. In this addition to the Bad Map Projections series, Randall has blended two different countries — the United States of America and Australia — into one.

As with a number of Bad Map Projections, the primary joke is the naming of this ''as'' a "map projection". Its depiction is particularly similar to [[2807: Bad Map Projection: ABS(Longitude)]], in which geography is overlaid upon other geography. It also follows the practice of [[2256: Bad Map Projection: South America]], in which a general continental shape is forced upon other areas, with the general geographical outline of the 48 contiguous US states being merged with the political boundaries of Australia (with exceptions, most obviously Australia's Bass Strait being retained in lieu of the US's central Florida). At a further level of merging, the US states are repacked as subdivisions within the various Australian ones; as with the likes of [[2394: Contiguous 41 States]], it also takes some liberties with the relative neighboring positioning of some of these, although not by totally removing any of the actual {{w|contiguous United States}} in this instance. Alaska and Hawaii aren't included, likely because the 48 contiguous US states better match the shape and size of Australia as well as Australia having no such equivalents.

The map pokes fun at superficial and irrelevant similarities between features of the maps of the United States and Australia, such as the shape of the east coasts of {{w|New England}} and the {{w|Cape York Peninsula}}, and the distance to the southern tip of island of {{w|Tasmania}} and the length of the {{w|Florida}} {{w|peninsula}}. The end result is to illustrate a fanciful place which does not actually exist and thus would have limited worth for navigating either Australia or the USA, although navigation between two listed locations/areas drawn from the same original continent would at least be broadly possible (with the possibility of a few 'surprises' en route). The blending features cities from both countries on the map, e.g., San Francisco and Los Angeles (USA) close to Perth (Australia).

The {{w|states and territories of Australia}} are depicted with black lines/labels, while the {{w|states of the United States}} and such cities as are taken from either nation are marked with gray. The Australian states are labeled with their full names, but the American states are given only their postal abbreviations. (Mississippi is mislabeled as MI, in addition to Michigan's own correct usage, instead of the official MS.) Western Australia is usually abbreviated to WA, but the convention here leaves that unambiguously assigned to the US state of Washington. Idaho, for some reason, is not labeled at all, and neither is the Australian island state of Tasmania.

The title text makes a joke that this map does not preserve {{w|Equal-area projection|area}} or {{w|Conformal map projection|direction}} (typically, a map projection {{w|Map projection#Metric properties of maps|sacrifices one to preserve the other}}, or both to correctly depict a particular distance metric), but does preserve the city of Melbourne as a feature located on the map, near the actual location of {{w|Melbourne, Florida}}. Note that this is not the correct location of {{w|Melbourne}}, Australia, as it is far too much east in the bad map projection, but there is nothing to stop the shared Melbourne being entirely 'correct' and every ''other'' feature being shifted as a 'compromise'. The concept of a point being 'preserved', rather than actual dimensionally-meaningful quantities, is meaningless and just adds to the badness of the projection. There are other city names shared between the US and Australia, but they're not located at any obviously similar geographic locations; e.g., the location of Brisbane in the comic is based on the instance in {{w|Brisbane|Queensland}}, not {{w|Brisbane, California|California}} (potentially named after the main example) or {{w|Brisbane, North Dakota|North Dakota}}.

This is the second comic in October 2024 in which Tasmania appears, the first being [[2996: CIDABM]]. Both feature the major island groups in the Bass Strait, in this case perhaps intended as a sort of analogue to the {{w|Florida Keys}}, or else orphaned coastline features across the 'missing' segment of the US peninsula.

===Geographical relationships===
From west to east, the Australian states and territories contain the following U.S. states; the positions of Australian cities on the map are also listed:

{{w|Western Australia}} contains the following U.S. states:
*Arizona
*California
** {{w|Perth, Australia|Perth}} appears on the California coast, about halfway between {{w|Los Angeles}} and {{w|San Francisco}}.
* Colorado
* Idaho
* Montana
* Nevada
* New Mexico
* Oregon
* Utah
* Washington
* Wyoming

{{w|Northern Territory}} contains the following U.S. states:
* Illinois
* Iowa
* Kansas
* Michigan ({{w|Upper Peninsula}})
* Minnesota
** {{w|Darwin (Australia)|Darwin}} is positioned in northwestern Minnesota.
* Missouri
* Nebraska
* North Dakota
* South Dakota
* Wisconsin

{{w|South Australia}} contains the following U.S. states:
* Arkansas
* Louisiana
** {{w|Adelaide, Australia|Adelaide}} is located in the {{w|Mississippi River delta}} region of Louisiana.
* Oklahoma
* Texas

{{w|Queensland}} contains the following U.S. states and territories:
* Connecticut
* Delaware
* District of Columbia
* Indiana
* Kentucky
* Maine
* Maryland
* Massachusetts
* Michigan ({{w|Lower Peninsula}})
* New Hampshire
* New Jersey
* New York
* North Carolina
** {{w|Brisbane}} is located on the coast in southeast North Carolina.
* Ohio
* Pennsylvania
* Rhode Island
* Tennessee
* Vermont
* Virginia
* West Virginia

{{w|New South Wales}} contains the following U.S. states:

* Alabama
* Georgia
** {{w|Canberra}}, and presumably the rest of the {{w|Australian Capital Territory}}, is located in southeastern Georgia.
* Mississippi
* South Carolina
** {{w|Sydney, Australia|Sydney}} is located along the coast of South Carolina, near the location of {{w|Charleston, South Carolina|Charleston}}.

{{w|Victoria, Australia|Victoria}} and {{w|Tasmania}} combine to make up the U.S. state of Florida, which is now divided into two non-contiguous parts. As a result Tasmania, which has a {{w|Omission of Tasmania from maps of Australia|history of being omitted from maps of Australia}}, is displayed but not named. {{w|Melbourne}} is located in the southeast corner of Victorian Florida. Although Tasmania's largest city {{w|Hobart}} is not labeled, it could share the same general location of Miami on the map. Alaska and Hawaii, the two non-{{w|Contiguous United States|contiguous states}} of the United States, do not appear in the projection. Other major geographic distortions include:
* The U.S. now has two {{w|quadripoint}}s, with the intersection of Colorado, Kansas, Oklahoma, and New Mexico joining the existing {{w|Four Corners}}.
* Indiana has a border with Arkansas.
* Alabama and Mississippi have lost Gulf Coast access, as Florida has a border with Louisiana.
* Missouri has a north-south border with Oklahoma.
* {{w|Miami, Florida|Miami}} is separated from the lower 48 states, as it is now located in the non-contiguous Tasmanian Florida.

{{w|Ravioli}} are a kind of stuffed {{w|pasta}} comprising a filling enveloped in thin pasta dough, commonly square shaped, and serving as the object of this comic's table, which can be seen as a kind of {{w|confusion matrix}}. This comic compares four ravioli-shaped objects (square shaped objects with bulging cross-sections due to their filling) with some common actions associated with them.

{| class="wikitable" | style="background:#E6C3C3;"
! Ravioli-Shaped Objects
! scope="col"| Eat with a fork
! scope="col"| Rest your head on
! scope="col"| Puncture and slurp
! scope="col"| Install in your phone
|-
! scope="row"| {{w|Ravioli}}
| style="background:#C5E6C3;"|Ravioli pasta would indeed be suitable to be eaten with a fork, as shown.
|Ravioli pasta is not structurally strong enough to support the weight of a human head while reclining, and would break and spill its filling over one's head and the object one is resting on. It may also be covered in sauce, adding to the general mess.
|style="background:#FBF8CE;"|If the ravioli filling is liquid/pureed enough, one could slurp it out with a straw. however, it would be somewhat wasteful of the pasta element.
|Phones are not meant to run on ravioli. Stuffing a phone with a raviolo would cause it to break as shown, spilling the filling through the phone, which is a terrible idea.
|-
! scope="row"| {{w|Throw pillow}}
|Throw pillows are made of cloth and are inedible, whether one uses a fork or not.
| style="background:#C5E6C3;"|A throw pillow is meant to be used as head support while reclining on furniture.
|Throw pillows do not usually have liquids inside them. Hence, Cueball finds, to his dismay, that it's empty.
|Throw pillows are significantly bigger than phones and as such can't fit inside them, nor can typical pillows power them. As depicted, the attempt to force a pillow inside the phone has split the latter in half; the top half of the phone is visible on top of the pillow, and a bit of the bottom half can be seen beneath it.
|-
! scope="row"| {{w|Capri Sun}}
|Eating a pouch of sweetened juice with a fork would most likely simply pierce the pouch and spill the liquid all over Cueball.
|style="background:#FBF8CE;"|A Capri Sun would serve as a waterbed of sorts, and wouldn't be unduly uncomfortable in a pinch. However, it's still possible that the pouch could rupture and leave you with a sticky head and no support.
|style="background:#C5E6C3;"|Capri Suns are meant to be drunk like this, and are enjoyed by many.{{citation needed}}
|The phone shown is surrounded by spilled Capri Sun, implying that the attempt to force the two together punctured the pouch. The resulting spillage would most likely just result in the surface of the phone becoming annoyingly sticky, but if the liquid managed to get inside the phone (especially if the cover had been removed to try to put it in the compartment that usually holds the battery) it could cause a more significant and difficult to clean mess. Once actual power is provided (either an actual battery being subsequently used or the device offered external power by cable or inductance charger), the remaining residue could cause any number of further faults, and perhaps even critical component damage.
|-
! scope="row"| Bulging {{w|Lithium Battery}}
|Bulging lithium batteries are explosive hazards and should not be punctured lest they explode. Additionally the contents of the battery are toxic if one were to somehow manage to eat the burning bits of the battery.
|A lithium battery is a small, hard object, and a bulging one is no exception. Since the bulging comes from a buildup of heat and gas, (the primary gases being hydrogen and carbon dioxide), it would also be a constant fire hazard, which would not be conducive to relaxation.{{cn}} Lithium battery themed throw pillows, which bulge similarly to such batteries, do exist as a novelty item. Notably, these types of batteries are often referred to as "spicy pillows".
|Similarly to the 'eat with a fork' example, puncturing a bulging lithium battery is a bad idea.
|style="background:#C5E6C3;"|A bulging lithium battery could be installed in a phone, if one is willing to break the phone a bit (like the screen in the comic) to accommodate the bulging of the battery. Also a terrible idea, as operating the lithium battery in this condition may result in the battery [https://www.reading.ac.uk/health-safety-services/fire-safety/lithium-battery-information/i-have-a-swollen-lithium-ion-battery-what-should-i-do catching fire or worse]. More commonly, bulging batteries form inside the phone itself, causing it to bulge outwards.
Surprisingly, this square is marked in green rather than red or yellow, as the first thing one should do on noticing bulging of the battery is to uninstall it from any device that it is in. It is at least no longer good at holding/delivering its charge, and may even become at least as {{w|Lithium-ion battery#Fire hazard|hazardous}} as when used in all the other scenarios. This square may be marked in green because, although putting a bulging battery in a mobile phone is not normal usage, it's a situation that can arise ''from'' normal usage when a "healthy" battery begins to fail.
Perhaps this is an [[:Category:xkcd Phones|xkcd phone]], and these are considered features, such as 'integrated hand warmer' and 'dynamic expansion'.
|}

The title text refers to the {{w|NFPA 704}} diagram for hazardous materials, a diamond figure put out by the {{w|National Fire Protection Association}} showing four kinds of fire hazards. A ravioli that touched all four quadrants would be a health hazard, fire hazard, and demonstrate instability, and have some other miscellaneous hazard(s). The NFPA diamond was previously mentioned in [[2638: Extended NFPA Hazard Diamond]].

2995: University Commas

2024-10-08T13:15:35Z

172.70.163.99: /* Explanation */

{{comic
| number = 2995
| date = October 7, 2024
| title = University Commas
| image = university_commas_2x.png
| imagesize = 580x273px
| noexpand = true
| titletext = The distinctive 'UCLA comma' and 'Michigan comma' are a long string of commas at the start and end of the sentence respectively.
}}

==Explanation==
{{incomplete|Created by an OXFORD-TRAINED BOT COMMA - Please change this comment when editing this page. Do NOT delete this tag too soon.}}

The use of commas in the English language is {{w|Comma#Uses in English|famously disputed}}, most relevantly among publishers and academics. This comic imagines that all possible (and impossible) comma positions in an example sentence are associated with different universities. This applies to commas which should ''always'' be present in a list, optional commas elsewhere in the sentence (which have nothing to do with a list, such as after the word "please") and blatantly erroneous commas (which should ''never'' be present in a sentence, e.g. immediately prior to the {{w|full stop}}/period).

The Oxford comma (a.k.a. {{w|Serial comma}} or, despite how this comic represents it, the ''actual'' Harvard comma) is a comma between the penultimate item in a list and its conjunction (typically ''and'' or ''or''), to echo all the commas (at least one) that act as {{w|Comma#List separator and the serial (Oxford) comma|placeholders for the conjunction}} in-between all prior members of the list. For instance, you might write "red, white, and blue" (with the Oxford comma) or "red, white and blue" (without it). Some style guides, such as ''{{w|The Oxford Style Manual}}'' published by {{w|Oxford University Press}}, (unsurprisingly) recommend using it, while other similarly authoritative guides recommend against it. Though even those with either recommendation may suggest its (non-)use in situations where this avoids an ambiguity arising from the normally recommended choice.

One {{w|Serial comma#Ambiguity|common example}} showing the need for an Oxford comma is "To my parents, Ayn Rand''',''' and God". Without the comma (as in: "To my parents, Ayn Rand and God"), it may read that the author's parents are Ayn Rand and God. If such confusion is to be avoided, reordering the list is a common way to avoid ambiguity, for example, "To Ayn Rand, God and my parents" is one such reordering. However, the use of an Oxford comma in this version might imply the deification of Ayn Rand.

Conversely, if the sentence was instead to be "To my mother, Ayn Rand, and God", with such a comma, there arises the possibility of an assertion that one's mother is Ayn Rand, whereas "To my mother, Ayn Rand and God" does not let one fall into that trap.

In the most common interpretation the example sentence reads (with proper punctuation and bracketed Oxford comma): "Please buy apples, mac and cheese, milk[,] and bread."

However, most of the commas are possible punctuation marks in a specific pragmatic reading of the sentence:

{| class="wikitable" style="margin:auto"
|-
! Comma name !! Notation !! Explanation
|-
| Harvard comma || Please, buy apples, mac and cheese, milk[,] and bread. || Emphatic plea, marked by a sub-clause separator. (Note that "Harvard comma" is already a common synonym for the Oxford comma, in its context.)
{{w|Harvard University}} is one of eight {{w|Ivy League}} universities in the United States.
|-
| Yale comma || Please buy, apples, mac and cheese, milk[,] and bread. || A merchant's plea to their customer, marked by a sub-clause separator.
{{w|Yale University}} is one of eight Ivy League universities in the United States.

{{w|Princeton University}} is one of eight Ivy League universities in the United States.
|-
| MIT comma || (Please, buy, apples, mac, and, cheese, milk, and, bread,.) || Possible reference to [https://stackoverflow.com/questions/11597901/why-are-trailing-commas-allowed-in-a-list trailing commas sometimes used in programming], which would be associated with a university highly specialized in technology.
The {{w|Massachusetts Institute of Technology}} is one of the prominant universities in the United States.
|-
| UCLA/Michigan comma(s) || (,,,…,,,Please, buy, apples, mac, and, cheese, milk, and, bread,.,,,…,,,) || '''Title text proposal''', each establishment being perhaps responsible for both or either sets of commas.

The {{w|University of California, Los Angeles}} and the {{w|University of Michigan}} are two more well known universities in the United States.

Depending upon who you talk to, the two establishments referenced by the title text may not be considered quite as prominant or outstanding as the Ivy League universities, or others mentioned here, hence their relegation to title text punchline. But (actual Ivy Leaguers) {{w|Brown University}}, {{w|Dartmouth College}} and the {{w|University of Pennsylvania}} were not referenced at all, for one reason or another; for example, the very idea of a "Brown comma" might more readily resonate with the concept of the {{w|Brown note}}.

==Trivia==
[[Randall]] appears to be a fairly regular user of the Serial/Oxford Comma, himself, with the most recent example being in the title text of [[2985: Craters]]. This is clearly out of habit or preference, as it is not required for clarification purposes. But clearly he also appreciates the conflicting viewpoints inherent to such a style opinion. He later completely avoided the use of list-commas entirely in a (three-part) list within the comic text of the successive [[2986: Every Scientific Field]], possibly for rhetorical reasons.

This very wiki currently reminds anyone editing a page that their contributions "may be edited, altered, or removed", which is also not a syntactical necessity beyond adherence to the Oxford styling. Later, in the same paragraph of text, it also uses structure of "…, or … or …", but for different grammatical reasons that are unrelated to serial/list commas.

172.70.163.99: Restoring my actual indents. (I wrote the initial :, :*s and concluding : bits, note where the sole signature is.

As Wikipedia notes, the {{w|Harvard comma}} is actually a thing, and synonymous with the Oxford comma. It's hard to understand whether Randall was just ignoring that.
It's interesting to also look at how the various commas are meaningful. For instance, the Yale comma here appears to be just plain ungrammatical, you'd never put a comma between a verb and a its direct object; similarly the Cambridge comma and Princeton commas are ungrammatical, you'd never put one after the word "and." The Stanford comma is unambiguously normal and it's not clear how you could have such a list without it (absent replacement with a [Stanford?] semicolon). The Columbia comma is being used to separate "mac and cheese" into "mac, and[,] cheese" which changes the semantic meaning (arguably into something meaningless, but maybe we're listing Apple Computers or even Macintosh apple fruit abbreviated). The MIT comma is a cute programming joke for multiline lists. Maybe there are hidden trick meanings (like MIT) I'm missing.

:On their own, few of them are intrinsically bad, in the right context.
:*"Please, buy" - valid comma. Prefixed subclause (general plea).
:*"Please buy, apples" - valid comma (more specific plea).
:*"apples, mac" - valid comma (list-type).
:*"mac, and" - valid comma (potentially a conjunctive sub-clause).
:*"mac and, cheese" - valid comma (potentially a post-conjunctive sub-clause).
:*"and cheese, milk" - valid comma (follow-up sub-clause).
:*"cheese, milk, and" - Oxford comma. (Thus invalid, by default. IMO.)
:*"milk and, bread." - ...would be valid, as above, except for the sentence ending.
:*"and bread,." - Ok. Definitely the worst. (Except for the Oxford Comma, which is still worserer!)
:Obviously, combinations of them (or counterpart lack of them, in some cases) can clash badly. Some can work well together, but using ()s, ;s or feetnete* is often better than diving in and out of sub-clauses in the midst of a comma-bound list and potentially making it ambiguous whether you're diving in/out of a clarifying aside or replacing a non-terminating conjunction or perhaps one of the other usages to which a comma might apply.

The UCLA comma may refer to the 8 clap, a chant at UCLA which is begins with a string of 8 claps.
[[Special:Contributions/172.68.245.206|172.68.245.206]] 05:11, 8 October 2024 (UTC)

I thought the UCLA & Michigan commas referred to quotes within citations. This isn't uncommon in literary studies, where you quote articles quoting books. Depending on your quotation style, this can result in a long string of 3-4 "commas" (as in: short lines in punctuation marks). If you place the quote between actual commas, make that 4-5.

}}

==Explanation==
This comic shows a number of common events, arranged in a grid. Each of the events flashes with its average frequency.

For example, statistically a child is born somewhere on the world approximately every 0.24 seconds, or four times per second. Therefore, the tile "One birth" blinks about 4 times per second.

The title text refers to the {{w|Pitch drop experiment}} which measures the flow of a piece of pitch over many years. At room temperature, tar pitch flows at a very slow rate, taking several years to form a single drop. The title text jokes that Randall tried to include a tile that flashes about once every {{w|decade|ten years}}, but the tiles are all {{w|Animated GIF|animated GIFs}} and while the file format supports animations of any length, the resulting file would be too big (at least 10 megabytes).

A thorough analysis of the frequencies present in this comic and how they relate to the underlying technology (the GIF format) was published as [http://notebooks.jsvine.com/reverse-engineering-xkcd-frequency/ Reverse Engineering xkcd's 'Frequency'].

The table below lists all the events and their periods/frequencies (computed from the GIF loop times). Some events make reference to other comics.

Talk:Randall Munroe

2024-09-30T02:28:59Z

172.70.163.99: /* Navbox */ new section

In comic 541 (TED Talk), Randall uses a Cueball character to refer to himself. How should this be included in the Wiki? Cited: http://xkcd.com/541/ [[User:AWiseGuy|AWiseGuy]] ([[User talk:AWiseGuy|talk]]) 21:50, 1 September 2012 (UTC)

:Hrm... I would suppose it would be something along the lines of this "In comic 541, Randall uses Cueball to refer to himeself." (with all of the links and stuff). Which is pretty exactly much what you wrote. That's how I think it should be done. But where to place it? Seeing as we have very little content as is, just put it at the bottom in the "main" part, and over time it'll fall into place as more content is added, probably. That's my two [insert monetary value here]s. {{User:Grep/signature|04:10, 25 February 2014}}

Randall needs a proper introduction here. This article should be much more serious — based on the English Wiki.--[[User:Dgbrt|Dgbrt]] ([[User talk:Dgbrt|talk]]) 21:25, 25 February 2014 (UTC)

I think Randall would find no higher compliment than to have a wiki article about him full of "citation needed" tags :D --[[User:Alcatraz ii|Alcatraz ii]] ([[User talk:Alcatraz ii|talk]]) 02:05, 11 October 2014 (UTC)
== Complete? ==

I'm not suggesting we're at that point right now, but what is the goal for this article to be deemed "complete?" as a bio of living person is rarely going to ever be "complete".

This is the xkcd wiki, so I would argue that if there was going to be a thorough and complete Randall article anywhere, it would be here... so at very least it probably ought to be more thorough than his general wikipedia page...

== Quaker reference? ==

There is no reference for Munroe being a Quaker except a footnote in a joke comic. Additionally, engineering is an, um, /unusual/ career for a parent who is a Quaker. This is likely an attempt from Munroe to generate a case of citogenesis (https://en.wikipedia.org/wiki/Wikipedia:List_of_citogenesis_incidents, https://en.wikipedia.org/wiki/Circular_reporting, https://xkcd.com/978/) as a small-scale Wikipedia prank.

== A couple of UK radio 'appearances'... ==

Might be worth a listing, on the proper page, but I leave it to someone else to work out how. Randall has featured in two (at least) BBC Radio 4 programmes ("programs", if you wish), in the last few days:
* The Infinite Monkey Cage, a general science-explainer-with-comedy show, this episode being around the theme of how to use mathematics in interesting ways. A somewhat anarchic (loosely planned) stream of thoughts in the presence of an audience.
* The Museum Of Curiosity, a comedy-interview/conversation show with a science bent. This is a more introverted casual conversation (no audience, but cross-talk) following its general template of first asking each guest a little about themselves and then asking them each to present 'something' as a talking point.
In both formats, Randall is one of a small panel of guests (and a pair of hosts, interestingly), and only directly contributes to about a third of each half-hour episode, but ends up talking about some of his work (especially about a lot of soup) in both. He's not the most talkative, in either case, but he holds his own and imparts his own wisdom sufficiently well. I haven't thoroughly searched yet to see if there were/will be more broadcasts with him in other BBC radio (or TV?) shows, while he was obviously at the forefront of the guest-bookers' thoughts; the [https://www.bbc.co.uk/search?q=Randall+Monroe obvious search] seems to be too title-orientated to extract "...with guest" mentions.

At least for the time being (and perhaps subject to some geographic browsing restrictions) the two episode links that might be useful (at least as a jumping-off point) are [https://www.bbc.co.uk/programmes/p0f1wc06 here] and [https://www.bbc.co.uk/programmes/m001jsdr here]. The former is also a published podcast, so should be freely found in that sphere of downloadables. And then there's the whole BBC Sounds platform, if you can and do access that. And the usual schedual of repeat broadcasts will happen, within the week. TIMC on Thursday (9/Mar/2023) 16:00GMT on R4, TMOC on Sunday (12/Mar) shortly after noon, ditto. (Further future readers might be lucky with somewhere like R4Extra having either series, if not precise episode, finding an archive slot at some handy but so far indeterminate point in their own near-futures.)

...anyway, FYI, for anyone who finds this useful news, or a point of historic record. [[Special:Contributions/172.71.178.64|172.71.178.64]]

It seemed that Randall had discovered Explain XKCD. [[User:ClassicalGames|ClassicalGames]] ([[User talk:ClassicalGames|talk]]) 09:36, 30 July 2023 (UTC)

:There usually seems to be a point of contact with the previous comic. That a connection is usually there means it probably isn't coincidental but is part of the ingredients for making each new comic. So yes they do seem random and arbitrary because the content of the connection doesn't mean anything. The point is just that every comic is connected to the previous comic. The explanations of the connections may be incorrect. I thought I'd put these connection sections in to see how people feel about having a regular connection section.

Anyone want to mention that this is probably referencing is a weird quirk of the films? We never see Luke construct a lightsaber (unless I missed something), and it's easy to assume that it's actually... I think Ben Kenobi's or Yoda's, maybe (for prequel enthusiasts) even Qui Gon's... After all, if Obi kept Anakin's, maybe he'd also keep Qui-Gon's, and any others, and end up leaving at least one green sabre on the Falcoln. Anyway, my point is, Randall noticed that this line of dialogue isn't really explained, and Luke is probably going along with Darth's assumption to save face... And then took the awkward situation to new heights. I can't tell if I'm being a total idiot here or if I'm on to something. Or option three, it's something glaringly obvious but needs a mention to explain the comic in context [[Special:Contributions/141.101.99.234|141.101.99.234]] 10:29, 21 July 2014 (UTC)
:Vader would probably recognize his mentors' lightsabers at first glance. Yes, it could be another unknown dead Jedi's saber, but it just as likely that Luke constructed one of his own, given he does not react in an obvious way to the suggestion. (Ignoring the Star Wars EU, which probably details exactly how Luke constructed the device.) Besides, we are shown Kenobi's, Yoda's and QG's lightsabers in the movies.[[Special:Contributions/103.22.201.239|103.22.201.239]] 11:39, 21 July 2014 (UTC)
:There exists a deleted scene from Star Wars VI that shows Luke building his new lightsaber: [https://www.youtube.com/watch?v=_ayT0EZwbks] [[Special:Contributions/108.162.254.53|108.162.254.53]] 13:45, 21 July 2014 (UTC)
:: Why would we need to see him build it? He lost his in the previous film. And he now has a snazzy new green one, along with much improved skill. The obvious conclusion is he built it. Vader then sees it and confirms that this is a mark Luke has gotten stronger. There is no reason to doubt that he built it. And before the prequels and such, we wouldn't have imagined there were thousands lying around. Now everyone and anyone has a light saber even up to Luke's time. When the movie came out, it was never clear how many Jedi there ever were. But it seemed to have been a very small number. [[Special:Contributions/108.162.215.212|108.162.215.212]] 23:49, 21 July 2014 (UTC)
:: I may be (mis)remembering something from the D6-based Star Wars tabletop RPG system (1980s, prior to this current D20 malarky), or something else "canon-derived-but-not-actually-canon" but ''personally'' creating one's own lightsabre is supposed to be something special. Obtaining/refining the crystals/whatever and tuning the device to work better with one's own Force Ability makes for a more harmonious relationship between Jedi/Apprentice Jedi and his or her weapon. Luke starts off 'raw' in the force (only with the innate and untrained ability) and with another individual's device (albeit his father's, which may count for something, the way these things work) but then like the various mythological instances of warrior-cum-blacksmiths (or blacksmith-cum-warriors) forging their own blade, something (even if only the Law of Narrativium) makes this self-made artefact singularly suitable for the fighting style of the creator/wielder. Or allows them to tune their still developing fighting style to the 'personality' of the weapon, if it is a two-way street.
:: Naturally, how far any of this can be extended towards the ''Fleshlight'' is very much arguable. Although if ''it'' is personally designed and built, to suit their own 'needs' then it's probably much better at the function it is intended to fulfil than an off-the-shelf or a (*shudder*) borrowed or ''hand-me-down'' one... [[Special:Contributions/141.101.99.233|141.101.99.233]] 00:08, 22 July 2014 (UTC)
:Boy, we're plumbing the depths of Star Wars geekdom here, aren't we? :) I think one other thing you folks are overlooking is that Vader is ''smart'' and ''powerful''. He can see and deduce things that most other people can't, mostly due to his powerful connection to the Force. In the movie, I believe that when he says "I see you've constructed a new light saber", he's not only remarking on its visible newness, but he properly senses Luke's memory of having done so. This fits, given a number of other lines later in the movie where Vader remarks on Luke's feelings, especially in "betraying" Leia as his sister. So even more than when he sees the saber itself, Vader probably knew well ahead of time that Luke had built one, part of his "rite of passage" to become a Jedi. (Personally, all of this makes the fleshlight joke that much funnier, IMO. :)) [[User:KieferSkunk|KieferSkunk]] ([[User talk:KieferSkunk|talk]]) 16:02, 22 July 2014 (UTC)
:Besides the evidence that others have brought that Luke did in fact construct his own lightsaber, we know that Luke's new lightsaber cannot be Ben Kenobi's since his lightsaber is blue, while Luke's lightsaber is green. Yoda's lightsaber is also green, but he lost it in his duel with the Emperor and never seems to have recovered it, and it is additionally much shorter than Luke's. Qui-Gon Jinn's lightsaber presumably fell into the shaft in the Plasma Refinery Complex, and there is no indication that it was every found again. Besides, the hilts of the lightsabers are visually different, especially insofar as Luke's lightsaber has a prominent "switch." {{unsigned|IcarusProblem|03:32, 15 December 2023}}
